<h3>Details:</h3>
<ul>
<li>
<h4>FFI:</h4>
</li>
</ul>
<blockquote>
<ul type="circle">
<li>A complete overhaul of the library interfaces and the glue-code generator
(ml-nlffigen). The implementation now scales much better, making it
possible to target huge C libraries such as gtk+ etc. (See the README file
under src/ml-nlffigen.)</li>
<li>ML represenation types have been streamlined.</li>
<li>Getter and setter functions work with concrete values, not abstract
ones where possible.</li>
<li>WORD-style bit-operations on INTEGER representations added.</li>
<li>Ml-nlffigen command line more flexible (see README file).</li>
<li>C_Debug added as an alternative to structure C. The difference
is that it always checks for NULL on pointer-dereference operations.</li>
<li>DynLinkage.open_lib' added. This function takes an additional
list of library handles. This is used for expressing inter-library
(symbol-resolution-)dependencies.</li>
<li>bug fixes</li>
</ul>
</blockquote>
<ul>
<li>
<h4>MLRISC:</h4>
</li>
<ul>
<li>There is a dramatic simplification in the interface to the register
allocator for RISC architectures as a result of making parallel copy instructions
explicit. </li>
<li>Bugs in x86-fast-fp have been fixed. It is now turned on
by default in SML/NJ.</li>
<li>Changed the representation of instructions from being fully abstract
to being partially concrete. See HISTORY file for more details.</li>
<li>Removed the native COPY and FCOPY instructions from all the architectures
and replaced it with the explicit COPY instruction from the previous commit.</li>
<li>Since COPY instructions are no longer native to the architecture,
a generic functor can be used to implement the expandCopies function.</li>
<li>Allowed EXPORT and IMPORT pseudo-op declarations to appear inside
a TEXT segment.</li>
<li>bug fixes<br>
</li>
</ul>
</ul>
<ul>
<li>
<h4>misc:</h4>
</li>
<ul>
<li>Allen Leung's "nowhere" tool added.</li>
<li>Minor modifications to pgraph.</li>
<li>rounding mode-related bug fixed in Basis library</li>
</ul>
</ul>
